SD-WAN technology comes with its own set of risks, including cost reduction and management. IT teams must well anticipate these difficulties.
Fremont, CA: Software-defined WAN (SD-WAN) is a feature-rich technology that combines networking, security, reporting, and management into a single platform. However, potential users should be aware of the hurdles and risks associated with SD-WAN deployment. Vendor selection, underlay provisioning, cloud connectivity, cost reduction, and management are all problems that must be considered while considering SD-WAN vendors, in addition to specific requirements.
Some challenges of evaluating SD-WAN vendors are:
Selection of vendors
The first problem with SD-WAN is deciding which vendor to use. Most IT decision-makers will start their SD-WAN research by looking into the top providers. Due to the abundance of marketing in the SD-WAN product field, this first step is challenging.
Provisioning on the side
It makes sense for SD-WAN to go from private WAN technologies like MPLS to the internet as the default connectivity choice. Almost every company is moving to the public cloud first, whether it's for SaaS, IaaS, or PaaS. The SD-WAN difficulty is determining which underlay service providers are best suited to a company's locations, as well as whether to use a single IP backbone or a multi-ISP architecture.
AWS, Microsoft Azure, or Google Cloud Platform connections are required in practically all SD-WAN vendor selection projects. When it comes to their capacity to access cloud services, SD-WAN manufacturers will generally fall into some particular categories.
One of the key drivers and marketing claims related to SD-WAN is cost reduction. Cost reduction, on the other hand, is frequently not measured in bottom-line savings and necessitates the evaluation of the entire benefit to the company. Adopting SD-WAN with SASE, for example, allows for more efficient working procedures. While enabling customers to access programs rapidly may not appear on the budget, the overall impact on the business might be significant.
The distinctions between DIY, co-managed, and fully managed SD-WAN are becoming blurred due to SD-WAN. Businesses do not have to choose their management level in the same manner they did in the past. Vendors who own their entire technology stack can assist customers in managing their WANs based on their specific needs. Vendors are ideally positioned to cope with any requirement across all levels of managed services since they retain control of the technology. SD-WAN management interfaces make it easier for IT teams to handle changes.
